So I got the patch queue up and running and it's functioning correctly
on the box I tested it with (although its not a super interesting box:
TSC is unstable and it only has ACPI PM).

Although I've not been able to test changing clocksources, I assume you
gave that a whirl? I'll test that as soon as I can get access to a TSC
friendly box.

Once the "cycles_last = 0" fix is in to make sure TSC boxes work, I
think this set should be ok to go in.

thanks
